MCAN Phase 1 Program Sites

The MCAN Phase I Program Sites were five innovative childhood asthma programs that implemented evidence-based interventions in low-income and medically underserved communities in Chicago, Los Angeles, Philadelphia, New York City, and San Juan, Puerto Rico. Over a 4-year period, through cooperative agreements funded by MCAN, these programs delivered services to children with poorly controlled asthma who had multiple ER visits and/or hospitalizations. 



MCAN Phase I Program Sites were selected through a competitive application process issued by the Merck Foundation. Read the Call for Proposals to learn more about the process and criteria.



RTI International conducted a cross-site evaluation of the asthma intervention outcomes of MCAN Phase I Program Sites using a mixed methods approach.  One of the data sources, the Common Data Elements Survey, was administered to parents and caregivers at baseline, 6 and 12 months.

The cross-site evaluation showed a consistent pattern of improvement across all measured outcomes, including symptoms, hospital and emergency department use, school absences, and caregiver confidence. To learn more about the design, implementation and outcomes from the MCAN Phase I Program sites read the Translation of Evidence-Based Pediatric Asthma Interventions in Community Settings: The MCAN Experience.
